Sessions now detailed

After some fighting with multi-threading issues, texture renderer and Line anti-aliasing, I now have CPU consumption detail appearing in the right side of the screen. I've been inspired from Ghost In The Shell SAC (which contains great ideas about GUI).

In the lower left part of the screen, we can see the active number of sessions, ie the number of connected ACTIVE sessions:



The number of detailed sessions is up to 5 but I guess I could display more.

Regarding the displayed information, I may add other ones (Logical IO, Physical IO...) :o)
